' Application filed August '7 1890. Serial No. 361,252- (No model.) Patented in Belgium June 30, 1890, No. 91,090; in Spain y 1,1890,N0.11,0l1; in Italy July 7, 1890, No. 27,880; in Luxemburg June 7,1890,N0. 1,299, and in Switzerland July 25,

To all whom it may concern:

Be it known that I, PAUL DE SUsINI, a citizen of France, residing at Paris,France, have invented certain new and useful Improvements in Motor-Engines Worked by the Vapor of Ether or other Volatile Liquids, (for which I have obtained patents in Belgium, dated June 30, 1890, No. 91,090; in Italy, dated July 7, 1890, No. 27,880; in Spain, dated July 4, 1890, No. 11,011 in Switzerland, dated July 25, 1890, N 0. 2,429, and in Luxemburg, dated June 7, 1890, No. 1,299,) of which the following is a specification.

My invention relates to an improved construction of motor-engine worked by the vapor of volatile liquids, such as ether. An essential characteristic of the improved construction consists in that its vapor'generator, its feed-conduit, and the motor-engine are all immersed in a bath of a suitable fluid inclosed in an air-tight casing and in that the use of stufing-boxes is avoided, so that no leakage of vapor can occur. In addition, the working parts being immersed in glycerine, they are effectually lubricated in an automatic and reliable manner, and consequently requiring no supervision. The body or bodies of liquid or combinations of liquids which thus isolate the generator and the motor-engine from the surrounding air is or are contained in a casing so constructed as to constitute a thermo-si phon or two thermo-siphons. The glycerine or other liquid surrounding the generator being heated directly byafire transmitsits heat to the ether or other volatile liquid of the generator, andthevaporthusproducedpassesthroughthe feed pipe or passage to the motor-engine,which is also surrounded by glycerine, this being made to circulate in like manner from the casing surrounding the generator to that surrounding the motor-engine, and after having flowed in a downward direction therein it passes back from the lower part of such casing to the casing of the generator, and so on continuously.

By the above-described means I avoid all condensation of the ether-vapor before it has completed its work. The ether-vapor-after doing work in the engine passes-through a conduit to an air surface condenser, where it flows in contact with very extended surfaces cooled by an air-current supplied by a fan, and, becoming immediately condensed, the resulting liquid ether flows down into a tank or receptacle below, that supplies the vaporgenerator. From this tank the liquid ether is then forced by a feed-pump into the vaporgenerator, from which it again passes in the form of vapor to the motor-engine, and so on continuously. It will thus be seen that a perfect utilization of the motive power produced by the generation and condensation of the ether-vapors is effected, resulting in a great economy of fuel as compared with other motor agents, while insuring perfect security in its use. Figures 1' to 5 of the accompanying drawings show the said construction.

Fig. 1 shows a vertical section of the motorengine and generator. Fig. 2 is a cross-see tion on line a b. Fig. 8 is a horizontal section on line 0 cl. Fig. 4 is a cross-section on line e f g 7t. Fig. 5 is a side view, and Fig. 6 is an enlarged sectional plan, of the cylinders and slide-valve gear of one of the cylinders and its slide-valve casing.

The motor-engine consists of two singleacting cylinders A B, the pistons O D of which have their rods 0 a coupled to one and the same cross-head E, acting upon a crankpin F on a crank-plate G of the shaft H, so that the pistons perform their strokes simultaneously, the one performing its working stroke while the other is performing its exhauststroke.

The shaft 11 is carried in bearings IJ, of which I is contained within the closed casing K,-filled with glycerine, While J is situated outside the casing on the base-plate of the machine, the shaft being carried through a stuffing-box in the side of the casing K, as shown.

The whole of the mechanism constituting the working parts of the motor-engine are inclosed in the casing K, and are consequently automatically lubricated by the glycerine therein.

The casing K communicates by a pipe L with the upper part of easing M of the vaporgenerator and by the pipe N with the lower part of this casing, which is also filled with glycerine. Thus, the glycerine in the casing M being heated by the fire-grate 0 when ICO the engine is working, a current of hot glycerinc will be established in the direction of the arrows, so as to constitute the continuous cycle of a thermo-siphon, the object of which is to prevent all condensation of ether in the supply-pipe P to the engine, as also in the cylinders A B, and thereby to enable the entire expansive force of the vapor generated to be utilized in acting upon the pistons O and D.

The vapor-generator Q is tubular, and the ether, which is contained in the space between the tubes q, is heated through the medium of the glycerinc, which circulates through the tubes q, and which is contained in the casing M. The generator is provided with all the usual safety apparatus, and on the pipe L is provided a safety-valve Z in order to prevent any excessive pressure from occurring in the glycerine contained therein before it has become completely dehydrated.

The ether-vapor is supplied to the cylinders by means of distributing slide-valves (Z and expansion slide-valves 0. These slide- 2 5 valves are of cylindrical form, and the vapor entering through the pipes I and passages 19 1), formed in the cylinders, passes into the cylindrical slide-valve casings and through the ports f into the spaces ,7 between the tightly- ;o fitting pistons h i, of which 7t belong to the distributing-valves and i to the expansionvalves. From the spaces g the vapor enters the interior of the expansion-valves through openings i, as shown, and thence through openings j 70 into the annular spaces Z between the two pistons m and n of the dis tributing-valves I], from which the vapor enters the cylinder through the ports 0.

The orifices j and 7a are of helical form in order to allow of the degree of expansion being varied by turning the expansion slidevalves 0 by means of an external hand-wheel t, the slide-valves (Z remaining stationary, by which means the moment of the closing of the supply-ports is advanced or retarded.

The expansion-valves e are connected together by a rod 6 and have tubular extensions c and are supported by rollers d, as shown at Fig. 5, in order to insure their accurate working and to reduce the friction due to their weight. For the same reason the crosshead E is supported upon rollers 6 The admission-slides d are connected together at their outer ends by the rod a, and all the 5 5 slide-valves are actuated by four eccentrics y, actuating two linlemotions .2" for reversing motion, one of which actuates the expansion-slides and the other the ad mission-slides, as shown. The link-motions are removed from the outside by means of a lever Z. At-

tcr working with expansion on the pistons C and D the vapor escapes into the annular spaces q and openings r in the passages 3, formed in one casting with the cylinders A 6 5 and 15. The exhaust vapor passes by the pipe R to the air-condenser S, where it comes in contact with internal extended refrigerating-surfaces formed by star-shaped ribs T, which are continuously cooled externally by a current of air passing through a surroundin g casing and supplied from a fan U through a pipe V, the fan being driven by the engine. The condensed ether collects at the bottom X of the condenser, which forms the feed-reservoir, from which it is drawn by the pump Y and forced into the generator.

Having thus described the nature of my invention and the best means I know for carryin g the same into practical effect,I claim" 1.
